Actually MIT did a computer generated model where they explain all the physics involved.

They explain exactly how they fell.

The two towers when hit with the planes . Sheared off the thermal coating o the steel support beams. Then the gas caused an inferno that wasn’t hot
enough to melt the beams outright, but was more than hot enough to bend them. Once the supports start to bend they loose the vertical stability which
starts the pancake effect.

The towers DONOT fall at free fall speeds. In the video you can watch debris out pace the buildings fall..

Building 7 was totally gutted from the backside of the pictures they like to show. A chunk of the towers landed on the roof taking out the back half
of the building. So the side we see as it falls is basically a shell. With only 2 1/2 walls still remaining.

Please do just stop with your continuous misinformation. It's getting old. Not as old as me, but it is getting old.

Let us instead promote the virtues of the US government and how they have all your (I am not a US citizen or resident) best interests at heart, almost
2 decades after the greatest "terrorist" attack was perpetrated with no action from aforementioned "authorities".

Yeah....

You forgot the passport they found. I'm only trying to help!

Quote where I ever said the things you implied.

A false argument by you.

I believe the government conspired to hide its incompetence concerning 9/11, and political ties with the Middle East that allowed the terrorists to
enter the USA.

I think NIST glosssed over the WTC construction, that WTC was not strictly built to the code of the time, WTC 7 structure used angles not commonly
used, and the buildings did not have traditional concrete cores that saved other building to cut building cost.

So how did the towers manage to fall perfectly into their own footprints? You do realize that a structural failure at that height of the building
would have induced rotation (moments) somewhere in the structure which would have then magnified the direction of motion of the building causing it to
fall laterally (horizontally)?

Please explain your theory as to how the buildings collapsed perfectly into their own footprints.

The towers did not fall in their own footprints. You realize the collapse of the towers destroyed, or damaged beyond economical repair, around 12
buildings.

Which columns, the columns at the floor of impact? Do you mean the idea that jet fuel leaked out and ignited? Do you realize that each floor had
firewalls in between floors? That is a building code requirement. The firewalls would have prevented any jet fuel from leaking between floors and
would have prevented the combustion from advancing between floors.

Either way it doesn't explain how the towers fell predominantly vertically. Any eccentricity in the failure of columns at the floors of impact would
have induced rotation into the structural system. Perhaps I was wrong implying they fell entirely in their own footprint, but the height of the towers
and a rotational eccentricity would have caused their collapse over several blocks.

WTC 7 was not examined by 911 Commission because IT WAS NOT IN THEIR SCOPE !!!

911 Commission was set up to examine the intelligence failures and the how that Bin Laden was able to place
terrorists in country and get flight training

WTC 7 was collateral damage in that it was not a primary target, it was damaged by collapse of WTC 1 which
ignited fires on multiple floors and cut off the water mains to area crippling sprinkler/standpipes to building
preventing FDNY from fighting the fires

After searching the building and discovering extent of damage and lack of water to fight the fires FDNY made
decision to abandon building in early afternoon

A transit setup to monitor the building detected that WTC 7 was "creeping' - structure moving out of plumb

It was this fact that caused FDNY to establish collapse zone around building and clear area at 3PM

By Mid afternoon word was out that FDNY was anticipating possible collapse of WTC 7

By 3pm had set up collapse zone around WTC 7 and cleared area

Actually heard the order being passed down to clear around WTC7 - this was from neighboring city FD (we were covering for them) who had crew working
at World Finance Center 3 (WFC 3) across West St from WTC 7

At approximately 2:00 pm, firefighters noticed a bulge in the southwest corner of 7 World Trade Center between the 10th and 13th floors, a sign that
the building was unstable and might collapse.[35] During the afternoon, firefighters also heard creaking sounds coming from the building.[36] Around
3:30 pm, FDNY Chief Daniel A. Nigro decided to halt rescue operations, surface removal, and searches along the surface of the debris near 7 World
Trade Center and evacuate the area due to concerns for the safety of personnel.[37]

10WHAT CAUSED BUILDING 7 TO COLLAPSE? Many firefighters reported seeing structural deformations of Building 7 hours before its collapse, including the
top FDNY fire Chief Daniel Nigro, who stated, “I feared a collapse of Building 7 (as did many on my staff). The collapse of WTC 1 damaged portions
of the lower floors of 7. Building 7 was built on a small number of large columns providing an open Atrium on the lower levels. Fires on many floors
of WTC 7 burned without sufficient water supply to attack them. For these reasons I made the decision (without consulting the owner, the mayor or
anyone else—as ranking fire officer, that decision was my responsibility) to clear a collapse zone surrounding the building and to stop all activity
within that zone.

It is well documented that WTC 7 was showing signs of structural failure before collapse.

There is no proof of detonations with the power to cut structural steel at WTC 7. Not by the indication of loud 140 db blasts, and no proof of
pressure waves from detonated explosives on video. The pressure waves should have carried distinct demolitions shrapnel.

There is no proof of thermite, and the proof presented is either:
1) Fraudulent
2) Lab results could not be replicated by other individuals.
3) The results of testing the WTC dust in an inert atmosphere which would prove thermite beyond a doubt never published.
4) The chain of custody of Jones samples appalling.

There is no proof that WTC 7 under went the floor by floor rigging of CD to remove the resistance that the truth movement claims had to happen to
achieve the observed rate of collapse.

It’s never been explained how a sophisticated and complex floor to floor detonation system in the WTC 7 would have maintained its integrity through
wall breaches, early minor structure failures, and extensive fires.
